In this example we will see how to read a file in Java using FileInputStream and BufferedInputStream. Here are the detailed steps that we have taken in the below code: 1) Created a File instance by providing the full path of the file(which we will read)
c om import java.io.FileReader; public class Main { public static void main(String[] argv) throws Exception { FileReader fr = new FileReader("text.txt"); int count; char chrs[] = new char[80]; do { count = fr.read(chrs); for (int i = 0; i < count; i++) System.out.print...
Java Copy In this example, we useArrays.sort()to sort an array of integers. The output shows the array sorted in ascending order. How to Sort a List in Java WithStream.sorted() Features in Java 8included the Stream API, which provides asorted()method that returns a stream consisting of...
To read the whole array, we are usingarr.lengthproperty. Thearray.length propertyreturns thenumber of elements in the array. In the following example, since the array contains four elements, this will return 4. Thus we can say that the for loop runs fromi=0 to i<4 ...
